Politico reports that hackers infiltrated the websites of dozens of House members overnight, replacing their usual pages with attacks on President Barack Obama.

The affected sites were taken down and replaced with a general House of Representatives “This site is currently undergoing maintenance. Please check back soon” message. Bay Area lawmakers whose sites are still down at this hour include Rep. Pete Stark, D-Fremont; Rep. Jerry McNerney, D-Pleasanton; Rep. Mike Honda, D-San Jose; and Rep. Zoe Lofgren, D-San Jose.
